preparation example Construction

[0028] The preparation method of biochar comprises the following steps:

[0029] 1) Place the peanut shells in the carbonization furnace, and control the temperature of the carbonization furnace to rise at a constant speed of 16°C / min;

[0030] 2) When the furnace temperature of the carbonization furnace reaches 450±30°C, stop heating and keep it warm for 30 minutes;

[0031] 3) Quickly cool down to room temperature to prepare biochar.

[0032] Rapid cooling refers to the cooling rate ≥ 10°C / min, usually 10°C / min. The reason for rapid cooling is that it can increase the porosity of biochar and increase the specific surface area. When the biochar prepared in this way is compounded with other components , some effective other ingredients will enter the pores of the biochar to improve the slow-release effect and prolong the life of the fertilizer.

[0033] The basic physical and chemical indicators of biochar are pH 8.45-8.55, total carbon content 48.30%-48.64%, total nitrogen ...

Abstract

The invention relates to a special organic fertilizer for tobacco. The special organic fertilizer comprises the following components in percentage by weight: 40-60% of charcoal, 10-20% of wormcast, 10-20% of humic acid and 10-20% of sesame cake fertilizer, wherein the charcoal is prepared from peanut shells by firing under low-temperature and anoxic conditions. According to the technical scheme, charcoal is mixed with wormcast, humic acid and sesame cake fertilizer. Through charcoal, wormcast, humic acid and sesame cake fertilizer, the carbon-nitrogen ratio of soil is increased, the organic matter content of the soil is increased, the soil fertility of flue-cured tobacco is improved, supply of tobacco nutrition is promoted, and growth and quality improvement of the flue-cured tobacco are promoted. The flue-cured tobacco yield, average price and first-class tobacco leaf proportion can be improved, the flue-cured tobacco output value and economic benefits are increased, chemical components of tobacco leaves are more coordinated, the internal quality of the tobacco leaves is improved, and the sensory quality of the tobacco leaves is remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, in particular to the field of fertilizers used in tobacco planting technology, in particular to a special organic fertilizer for tobacco. Background technique [0002] Soil is the basis of flue-cured tobacco production, but flue-cured tobacco production in my country is generally over-dependent on chemical fertilizers, which leads to serious degradation of tobacco planting soil, insufficient aroma components of tobacco leaves, and decline in quality. Therefore, improving the tobacco planting soil is an important way to improve the quality of tobacco leaves. Organic fertilizers contain a variety of beneficial microorganisms, which can improve soil structure, increase crop resistance, increase crop yield and output value, and improve the quality of flue-cured tobacco. The application of organic fertilizers can also improve the coordination between the internal components of tobacco leaves and i...
